Silicone rubber is used as an insulator with a silicone heating pad, and the interior contains a nickel-chromium alloy wire as the heating element, ensuring close contact with the heated object. The insulation layer consists of silicone rubber and fiberglass cloth, providing high electrical insulation performance. The electric heating pad features efficient heating, uniform temperature distribution, high thermal efficiency, durability, flexibility, ease of use, safety, and water resistance. Ideal for insulation applications in industrial equipment, pipelines, storage tanks, oil drum heating, automotive fuel tanks, water tanks, and battery anti-freeze protection. Silicone heating pads are lightweight, flexible, safe, and long-lasting. With excellent dielectric strength, they help reduce energy consumption during winter heating operations. Maximum temperature: 200C Operating voltage: DC 12V or 24V Power: 12W or 30W Resistance: 4.8 ohms Compatible with different voltages to achieve corresponding power output.
